To all whom t may concern: l

Be it known that I, GEORG KIRKEGAARD, a citizen of the United States, residing at the city .of New York, in the borough of Brooklyn and State ofV New York, have invented certain new land useful Improvements in Bottle-Stoppers, of which the following is a full,

clear, and exact description.

This invention relates to bottles and jar Stoppers of that general class in which a metal cap having a lining of packing material, suchv seal, can be readily removed therefrom without the use 'of any special tool and by simple hand manipulation. l

A further object of the invention is to provide a construction of stopper whereby the cap having been once removed from the receptacle can be replaced by hand a number of times and obtain a seal substantially as perfect as the ori 'nal seal.

With these objects in view the invention consists of 'the construction hereinafter described a'nd claimed.

In the accompanying drawings, Figure 1 is a pers ective view of my improved cap-stopper. Fig. 3 is a section of the u per part of abottle and the stopper ap lie thereto, and Fig. 4 is a sectional 'view o the cap along line 4 4 of Fig. 3 looking upward.

The stopper comprises acap consisting of a disk portion a, having an annular depending flange b, fornnng an inverted cup, Within which is placed a disk c of cork or other suitable ackin material. At three points aroun the ange b lsubstantially one hundred and`twenty degrees apart are formed.

fingers d, and one of the fingers is vextended to form a handle or tailpiece e. The arts so far described. are made out of a single piece of sheet metal, usually tin, and of considerable weight or body to afford stiffness and strength. Each of the fingers d is embossed or pressed in a peculiar manner, first,

to afford lugs to engage the bottle or jar, and,'

second, to aord Vstrength or stiness to the fingers for a purpose which will hereinafter appear. The holding-lugs j for engaging the ig. 2 is a side elevation of the same.

bottle are indicated by f. They projectinward radially at such a distance below the disk a as to engage the usual inclined shoulenoReKiaxEeAARo, or Naw YORK, N. Y., As'sieNoR or ONE-'HALF To 'i der g on the external surface of the bottle` neck, thus affording three points of-engavement between the cap and the -bottle or holding the former in place. For stiffening and strengthening the fingers the U-shaped ribs h are provided. These extend from points well over the edge of disk a downward around and below the holding-lugs Befiange b is also bulged outward above the projectionf, as indicated at i, so that the whole structure Aof the finger is far .more rigid vand strong than the remaining portions of the fiange b or the disk a. Upon the face of the lower or curved portion of the ribs h a further projection or nub j is formed for a purpose which will hereinafter appear.v

In fixin this stopper upon the bottle or jar origina ly a machine or tool is ordinarily s tween the arms of the ribs h the metal of the` employed which serves to first press downward upon the disk a to compress the packing material c a ainst the mouth pf the bottle and then to aterally and inwardly press against the lower ends of the fingers al to force the holding-lugs f into engagement with the annular shoulder g. To facilitate the operation of this machine or tool, the nubs j are provided, the jaws of the tool impinging against these nubs instead of against the rib h, and thus avoiding the flattening out of the latter. The cap thus secured to the bottle is held firmly in place by the strength of the fingers (Z, and in order to remove it from the bottle it is necessary to force outward at least i bottle the handlecan be forced outward suf' ficiently to release the lug associated with the handle, from the shou der g and permit the cap to be lifted.

IOO

If after opening the bottle it is desired lto reseal it, this operation can be readily performed by simply placing the cap over the mouth of the bottle and pressing downward upon the disk a with the hand or fingers until the fingers d snap under the shoulders g,

whereupon, by reason of the spring of the l cap containing pac ing material and having i chine or tool they will not thereafter of them- "fiange, said holding-fingers having inwardly- -rality of fingers extending downward from the tle an metal, the pressure of the lugs against the inclined shoulder g will draw t e cap downward sufficiently to efiectually seal the bottle.

The merit ofA the construction herein described resides in the fact that the material of the fingers d is so shaped as to be stronger and stiffer than the adJoinin metal inthe flange d and disk a,`so that W en the fingers have been originally set inward by the maselves yield and can only be forced outward by the yielding of the weaker materialv of theflange b and disk a immediately surrounding the fingers. In other words, the finger is stiff or rigid, while the surrounding metal is more or less yielding, and the locking position of the fingers is not changed or distorted by the removal of thecap from the bottle or by its replacement thereon. The only distortion that takes place is in the flange b and disk a, and this restores itself the moment the cap is seated on the bottle or removed therefrom.

Having described my invention, I claim- 1. A bottle-stopper comprising a metallic cap containing acking material and provided with a depen ing annular flange and with holding-fingers extending from and below said directed lugs to engage the neck of the bottle and being stiffened or reinforced from their lower extremities upward through the depth of said fiange, for the purpose described. l

- 2. A bottle-sto per comprising a metallic disk, an annular epending flange and a pluflange, said fingers having embossed or impressed ltherein U-shaped ribs the arms of which extend substantially from the edge of the disk to and around the lower extremity of the fingers, for the purpose set forth.`

3. A bottle-stop er comprising a metallic a. number of de ending fingers around its pel riphery, each nger having an inwardly-extending lug for enga ng the neck of the botalso strengt ening-ribs surrounding said lugs and'extending upward to the cap, substantially as described. 1

4; A bottle-stopper comprising a disk hav- 5o ling an annular depending flange, a number of 'thefarms of said rib and above said lug, for

the purpose set forth.

5. A, bottle-stopper comprising a metallic cap'containing packing material, a number of fingers depending from said cap, and having holding-lugs formed on their inner surfaces, and a Strengthening-rib surrounding said holding-lug and provided with a nub adapted. t0 be engaged by a fastening tool or machine.'

6. A bottle-stopper comprising a sheetmetal disk having a depending annular flange, integral depending holding-fingers provided with reinforcing means extending from the lower ends of the lingers across the width of the flange to the disk, and a handle or tailpiece extending from one of the fingers, for the purpose set forth.

7. A bottle-stopper comprising a sheetmetal capl containing packing material and having a depending flange, fingers depending from the lower edge of said flange and provided with a reinforcement extending from their lower ends upward through the width or depth of the flange, one of said fingers having a tailpiece provided with a reinforcement extending throughout its length and continuing through the length of the finger to which it is attached and the width of the flange, for the purpose set forth. 85

8. A bottle-stopper comprising a sheetmetal cover for the mouth. ofthe bottle and fingers extending from the edge of said cover and adapted to hold it upon thebottle, said fingers provided with reinforcing means extending into the body of the cover beyond the edge from which the fingers extend. l

In witness whereof I subscribe my signature in the presence offtwo witnesses.
